Abstract
The invention relates to a frequency dispersive antenna comprising radiating waveguides divided into three legs. The indirect angle between the first and second leg is greater than or equal to 90 degrees and less than 180 degrees, the direct angle between the second and third leg being greater than or equal to 90 degrees and less than 180 degrees. The antenna comprises a feed waveguide comprising a stack of elements divided into three adjacent legs, the direct angle between the first and second leg being greater than or equal to 90 degrees and less than 180 degrees, the indirect angle between the second and third leg being greater than or equal to 90 degrees and less than 180 degrees. In particular, the invention applies to an airborne antenna suitable for the detection and for the pinpointing of meteorological phenomena.
